Thanks for the information Alexander, 6MHz works for me as well. I've configured 2 RPi Model B with 6 MHz max SPI frequency and can ping back and forth with a packet loss rate of 1% to 8%, most often it is around 3%, rtt ~8.7 ms. Distance is about 1 - 2 meters. 2015-05-04 20:35 GMT+02:00 Alexander Aring <alex.aring@xxxxxxxxx>: > Hi, > > maybe you read the other mail about the RPi and openlabs transceiver > module. > > at86rf233 datasheet says 7.5 Mhz is the highest clock, but since the RPi > clock can run at 7.35 Mhz I expierence issues with the openlabs transceiver. > > Set the max spi clock to 6 Mhz solved this issue.
